Figure 3.

The distributions of three EEG power metrics. The first column shows distributions of the instantaneous power; the second column shows distributions of their log‐transforms. Solid lines: Measured distribution. Dotted lines: Normal approximation. First row (a,b): Distributions of power in a single time–frequency bin. Second row (c,d): Distributions of average power over a time–frequency window. Third row (e,f): Distributions of differences in average power (cf. baseline‐corrected averages).
